Abstract To predict the dynamic behaviour of structures under the effect of impact, we approach the dynamic problem in the form of a numerical simulation of impact on a cracked plate. Our choice is focused on a numerical simulation in order to examine the response of a cracked aluminium alloy plate impacted by a spherical steel projectile. The use of ANSYS® LS Dyn (dynamic explicit) software allows us to study this behaviour as a function of the boundary conditions, and the geometric parameters of a plate and the sphere, taking into account the variation of the crack length. A comparison is made with the case of a healthy plate without defects dynamically stressed under the same conditions. In addition, the calculation of the equivalent Von Mises stresses and equivalent elastic deformations are carried out. Keywords: • cracked plate • impact • dynamic • ANSYS LS Dyn • spherical projectile |
